through the roof. Fasteners have been in-,

vented, and to some extent used, for securing the free ends of the shingles to the roof, but

in so far as we are aware they have had a binding effect upon the shingle, inhibiting its freedom of thermal expansion or contrac tion thereby causing a warping of the shingle, making an unsightly roof and permitting water-to enter beneath the shingles. The present invention has for its principal object the provision of means for holding down the free end of the shingle while at the same time permitting freedom of motion of said free end so that the shingle may remain flat while accommodating itself to thermal expansion or contraction.

Another object ofthe invention is to pro vide a shingle fastener adapted to cooperate with a shingle having a pre-folded free end, the construction of said fastener permitting the positioning of the shingle and the securing of the same'in place without the necessity of bending the shingle onithe job along the line upon which the end is folded, as has been necessary in certain previously known shingle fasteners and results in the later development of a crack or break in the shingle along the line of fold.

A further object of the invention is the provision of a shingle and shingle fastener so arranged as to form a ventilating crevice between the edges of the shingle and the edges of the adjacent shingles of the underlying course when the shingle is in place relative to the fastener.

Another object of the invention is to construct a shingle fastener of the type indicated which is entirely concealed when the shingles are in place and which provides spacing means which renders the fastener self-allocatable. and also serves as a spacer between the edges of the folded end of the shingle and the edges of the adjacent shingles in the previously laid course. thus ensuring ventilation and perfect drainage.

avoiding dampness of the roof and thereby increasing the length of life oft-he shingles. 1

Otherobjects of the invention will appear as the description of the following illustra tive embodiments thereof proceeds.

In the drawings Figure 1 is aface viewof a portion of a roof shingled with flexible shingles and employing our invention.

Figure 2 is a section taken along .the line 22 of Figure 1. l

Figure 3 is a view similar to Figure 2 but showing the shingle in separated relation with respect to its fastening means.

Figure 4 is a perspective view showing one of the pre-folded shingles. i

Figure 5 is a perspective view of one embodimentofmy improved shingle fastener. Figures 6 and 7 are respectively plan and beneath views of a slightly modified form of the invention. it Referring now in detail to the several figures, the reference numeral 1 represents adjacent shingles of an underlying course having their adjacent corners 2, 2 in abutment, forming an inverted V-shaped valley 3. The shingle fastener 4", which is illustrated in Figure is placed over the abutting corners of said shingles and secured thereto in any suitable manner as by nails passing throng the apertures 5. In Figure 5 the apertures are shown as being pre-formed but inpractice it may be advantageous to drive the nails or other securing means directly through the material of the fastener. The fastener 4 is preferably made of sheet metal having on its under side a V-shaped depression 6 formed by pressing up the material of the fastener in a manner which will be clearly understood from an inspection of Figure 5. The V- shaped depression has preferably the same has and in positioning the fastener prior tosecuring the same in place, the V-sh aped'depression should be placed in coincidence with the V- shaped valley so as to form a pocket 9 for a corner 7 of the shingle 8. The depth of the pocket 9 is equal to the thickness ofthe adjacent shingles 1, plus the depth of the depression 6 so that there is ample room to permit the foldedcorncr 7 of the shingle 8 to slide into said pocket without binding and to befreely retained therein so as to permit unrestricted movement of the shingle in an up and down direction when expanding or contracting. The altitude of the folded corner of the shingle is preferably less thanthatofithe pocket soi'tliatventilating groovesorerevices are formed hetween edges of the shingle forming said corner and the? sides of thepocket, and of? the ad jacent shingles in the lower course. The corners of the fastener are,vby' preference, cut away diagonally to prevent them projecting beyond the supeiposed shingle. shin le8 is preferably folded at the factory while subjected to a proper degree" of? heat terpermit' t'hebending th'ereofwithoutbreaking'or cracking or the"flakingoff ofthe slate particles witli'wliicli the flexible shingles are frequently coated. The freedom of'movement' of the folded? corner 7. within the pocket 9 avoids the necessity of forcing' the shingle in place or straightening; it out: or in any' other way abusing". the pre f'ormed fold so thatthe shingle, when laid; is in. as perfect condition as when firsti manufactured; This cannot" be: said of shingles of which it is necessary to forcea: cor11er;beneatli the fastening-means. while the: shingle is in straight condition, the shingle being then folded over the fastening means;

F11- Figures 6 and TP have shown a form of 't-lieinvention which is. similar in its broad features to" that shown in Figure 5; but distinguished therefrom by liavingslits made inthe material adjacent? the apex and ends ofthe V shaped depression; the ma;- t'erial being bentdownwardly'attlie ends of such depression to form lugs 10 and 11'; Said lugs formspaeers for th'e fastener; the lugs 10 engaging'with" the upper edges of the adjacent shingles 1 above the abutting corners thereof, and the lugs 11 engaging the edges of" said adjacent shingles which form: the sides of the V-shaped valley 3; When the underturned corner? of" a prefoldedi shingle is inserted" into the pocket 9; the; edges of" said un'der-turned' cornerengagewiththe'liigs 11', preventing said' edges from coming into close' abutment with the edges of the adjacent shingles: ALt-i'ougli 12 isthusformed Whielrafford's a ventilating space between said edges; preventing the retension of dampness and preserving the life oftlie shingles While we have" hereiir disclosed what" we believe to he a: practical embodiment of our invention it is to be understood that it may be exemplifiediininumerous other alternative constructions without transcendingithe scope of the appended" claims.

Having described our invention what we elai1n as new and desiretosecureby Letters Patent, is

1'.- A shingle fastener comprising a plate adapted to overlie the juxtaposed corners of adjacent diagonally laid shingles in a course and having a depression in its lower face adliptedto coincide with: the valley between the lower" adjacent edges of saidE shingles to form: a pocket of greater depth than the tliicltuess of a shingle:

2. A shingle fastenercomprising a plate adapte'dto overlie the uxtaposed corners of adjacent diagonallylaid shingles in acourse a-n'd having a depression in its: lower face adapted tocoincid'e withthe'valley between the lowei adjacent' edges of sa-id" shingles to form apocket" ofgreater depth-than the thickncss of ar shingle, the sides of said pocket"terminating inedges which intersect theside and" bottom edges of'said fastener; saidfastenerbeing adapted'to'be secured to said a'djacent shingles.
